State in brief about the nuclear DNA

The nuclear DNA is distributed between two or more chromosomes, the number of which varies among different eukaryotes, and is characteristic of every organism. The yeast cell, for example, has 12- 18 chromosomes, while the human cell has 23 pairs of chromosomes. The nucleus is filled up with nucleoplasm, which contains several of the enzymes involved in the synthesis of nucleic acids. The nucleus also contains a roughly spherical body, the nucleolus, within which the RNA component of ribosomes is synthesised. The nucleus and its associated chromosomes undergo profound changes at the time of cell division, during which, the genetic material is duplicated and identical copies of it are shared between the two daughter cells.
